Subject: [PATCH 1/1] Drivers: hv: vmbus: Use the new infrastructure for
delivering VMBUS interrupts
Use the infrastructure for delivering VMBUS interrupts using a
special vector. With this patch, we can now properly handle
the VMBUS interrupts that can be delivered on any CPU. Also,
turn on interrupt load balancing as well.
This patch requires the infrastructure that was implemented in the patch:
X86: Handle Hyper-V vmbus interrupts as special hypervisor interrupts
Greg, Please apply this patch after 3.9-rc1.
